title: Analysis of factors affecting hematopoietic recovery after autologous bone marrow transplantation for lymphoma.
abstract: Thirty patients with relapsed lymphoma (14 Hodgkin's disease, 16 non-Hodgkin's lymphoma) who underwent autologous bone marrow transplantation (ABMT) were assessed for the effect of different parameters on the rate of hematologic recovery post-ABMT. There was no correlation between nucleated cells count or numbers of CFU-GM or BFU-E in the infused marrow on either neutrophil or platelet recovery times. Patients with lymphoma who received more salvage chemotherapy (greater than six cycles) prior to marrow harvest took significantly longer to recover neutrophils to greater than 0.5 x 10(9)/l (p = 0.0229) and platelets to greater than 20 x 10(9)/l (p = 0.0007) than patients who received less than five cycles of salvage chemotherapy prior to harvest. There was no significant correlation between underlying disease, use of total body irradiation or status of cytomegalovirus serology and recovery times post-ABMT. The results suggest that extensive salvage chemotherapy may result in considerable stem cell damage to marrow, and that potential ABMT candidates with lymphoma should undergo harvest of tumor-free bone marrow as soon as possible following first relapse.
